The research area covers developing a structural approach based on extensive single-crystal X-ray diffraction studies as a tool for designing and evaluating novel electrolyte systems. The method involves crystallization experiments of several solvates of selected heterocyclic salts and their crystal structure analysis correlated with spectroscopic measurements, electrochemical evaluation, and theoretical modeling. Understanding factors governing the self-organization of such systems in the solid phase is crucial in the characterization of new electrolytes. It is necessary for further development in this field, offering the possibility of planning research to find electrolytes with expected properties rationally. This subject perfectly fits the current trend of intense searches for concentrated and solid electrolytes with more favorable operational and safety parameters which respond to the rapid increase in demand for modern lithium-ion batteries.

My research group works on new materials for energy storage devices such as batteries and supercapacitors. The recent breakthrough studies of the group has led to the design and development of a novel family of Huckel-type salts for application in electrolytes used in lithium and/or sodium ion batteries. These conducting salts are based on anions that weaken coordination interactions between anion and cation in the structure, thus resulting in an increased ionic conductivity and cation transference number values, lower tendency towards formation of associates, and high tolerance to moisture. These conducting salts containing novel, proprietary anions are also functional as SEI modifiers and moisture absorbent/inside desiccants, present in electrolyte as a single additive or in a mixture with other environmentally friendly additives based on organosulphur compounds also designed in my research group. . Another area of interest deals with studies on a new class of proton solid conductors based on nonaqueous proton conducting gel polymeric electrolytes for application in electrochromic devices. This concept is currently used in super capacitors working below ambient temperature.
